A Dallas-Fort Worth, Texas, homeowner wanted the cast iron plumbing beneath a 1979 house replaced before it caused trouble. A $40,000 quote for the full job stood apart from two bids of $31,000 each, according to the homeowner in a thread from August 2026.
The homeowner reported no plumbing problems but wanted to avoid a future sewage backup that could damage flooring or drywall. For other Texas homeowners weighing a major drain replacement, this house shows why the price alone may not explain a bid: the work involved tunnels beneath the house, and the posted quotes had no item-by-item scope to compare.
